Claims. (Cl. 229-16) The present invention relates to combinationpaperboard berry boxes and snap lids therefor, and more particularly tosuch devices wherein the lid'retaining structure also serves as areinforcement for the top edges of the box.

The primary object of the invention is to provide a combination berrybox and snap lid therefor formed of paperboard in which the box willhave strength equal to or greater than that of a conventional woodenberry box.

Another object of the invention is to provide a paperboard combined boxand snap lid therefor in which the boxes are so formed that they can bevertically nested for shipment to the point of filling.

A still further object of the invention is to provide a paperboard berrybox and snap lid thereof which is inexpensive to manufacture, simple touse, and durable in hard service.

Other objects and advantages will become apparent in the followingspecification when considered in the light of the attached drawings, inwhich:

Figure 1 is a perspective view of the invention.

Figure 2 is a transverse cross-section taken along the line 22 of Figure1, looking in the direction of the arrows.

Figure 3 is a plan view of the blank from which the box incorporatingthe invention is formed.

Figure 4 is an enlarged fragmentary plan view of one corner of the boxillustrating the reinforcing construction.

Figure 5 is a plan view of the corner reinforcing element blank.

Referring now to the drawings in detail wherein like reference numeralsindicate like parts throughout the several figures, the referencenumeral indicates generally a box constructed in accordance with theteachings of the invention.

The box 10 is formed of paperboard and consists of a rectangular bottomwall 11 having opposite parallel side edges 12 and 13 connected byopposite parallel side edges 14 and 15. A plurality of side Walls 16,17,- 18 and 19 have their lower edges integrally joined to the sideedges 12, 14, 13 and 15, respectively, of the bottom wall 11. Each ofthe side walls 16, 17, 18 and 19 are provided with opposite spaced apartoutwardly flaring side edges 20 and 21. Each of the side walls 16, 17,18 and 19 are further provided with an inner fold line 22, a medial foldline 23, and an outer fold line 24. Each of the fold lines 22, 23 and 24being adjacent the outer edge 25 of each of the side walls 16, 17, 18and 19.

The side edges 21 of each of the side walls 16, 17, 18 and 19 areprovided with a laterally extending glue tab 26. Each corner of thebottom wall 11 is provided with a ventilation opening 27 which extendsinto the inner corners of the side walls 16, 17, 18 and 19, asillustrated in Figure 3, to ventilate the box 10.

The fold lines 22 and 23 in each of the side walls ice . 2 16, 17, 18and 19 delineate a horizontal flange 28 extending outwardly from theside walls 16, 17, 18 and 19. The fold lines 23 and 24 delineatetherebetween a vertically extending panel 29, the fold line 24delineates a second vertical panel 30 extending therefrom to the outeredge 25. The second vertical panel 30 is reverted along the fold line 24and is secured in parallel relation to the vertical panel 29, as bestillustrated in Figure 2.

The outer edge 25 of each of the sidewalls 16, 17, 18 and 19 isvertically spaced above the horizontal panel 28 establishing ahorizontal groove which is adapted to receive and hold the edges of apaperboard cover 31 with the paperboard cover 31 held to the box 10 bythe outer edges 25 of the side walls 16, 17, 18 and 19.

A corner reinforcing member generally indicated at 32 consists of agenerally rectangular blank having longitudinally extending spaced apartparallel fold lines 33 and 34 extending thereacross. A centrallypositioned V notch 35 extends inwardly from one side edge of the member32 intersecting the fold line 33. A second medially positioned notch 36extends inwardly from the opposite side wall and intersects the foldline 34. A vertically extending fold line 37 connects the apices of theV notches 35 and 36 and extends parallel to the end edges of the member32.

The V notch 35 establishes a pair of flaps 38 and 39 joined to alongitudinally extending body 40 along the fold line 33. The V notch 36establishes a pair of flaps 41 and 42 joined to the longitudinallyextending body 40 along the fold line 34. In the use of the reinforcingmember 32 the longitudinally extending body portion 40 is folded alongthe fold line 37 at a right angle, and glued to adjacent end portions ofthe vertically extending panels 29. The flaps 38 and 39 are foldedinwardly to overlie the vertically extending panels 30 and are gluedthereto. The flaps 41 and 42 are folded inwardly at right angles to thebody portion 40 and are glued in underlying relation to the horizontallyextending flanges 28, with the flaps 41 and 42 having their adjacentedges overlapping, as best illustrated in Figure 4.

The horizontally extending flanges 28 provide a reinforcement for theupper edges of the side walls 16, 17, 18 and 19 against horizontaldisplacement while the vertically extending portions 29 and 3t)reinforce these side walls 16, 17, 18 and 19 against verticaldisplacement. The provision of the reinforcing flanges 28 and portions29 and 30 provides a berry box formed of paperboard having unusualstrength characteristics such that the box 10 can be utilized for agreat variety of products in the grocery field as well as in otherfields.

Having thus described the preferred embodiment of the invention, itshould be understood that numerous structural modifications andadaptations may be resorted to without departing from the scope of theappended claims.

What is claimed is:

1. A combined paperboard box and snap lid therefor comprising arectangular bottom wall, a plurality of side walls having their bottomedges integrally joined to the side edges of said bottom wall, said sidewalls each having upwardly and outwardly flaring side edges, means onone of said side edges of each of said side walls for connecting saidone side edge to the adjacent other side edge of the adjacent side wall,a horizontally extending flange projecting outwardly from the upper edgeof each of said side Walls, a vertically extending panel projectingupwardly from the outer edge of each of said horizontal flanges, asecond vertically extending panel integrally joined to the upper edge ofsaid first vertically extending panel and secured thereto inwardlythereof in spaced relation to said horizontal flange, a corner connectorextending between adjacent end edges of said side walls, and a resilientcover having its side edges engaged between said horizontally extendingflanges and said second vertically of said bottom Wall and the lowercorners of said side walls are apertured for ventilation purposes.

4. A device as claimed in claim 1 wherein said corner connectorcomprises a longitudinallyextending portion secured to said verticallyextending panels, flaps overlying the top edge of said verticallyextending panels and engaged against the inner faces of said secondvertically extending panels, and a pair of flaps engaging under saidhorizontally extending flanges. g

5. A device as claimed in claim 1 wherein said cover isformedrectangularly and has an upwardly bowed arcuate configuration;
